Rose plant Jacale

ABSTRACT

A floribunda rose variety having compact, upright plant habit, large blooms of light pink, white and pale yellow blend, distinct fragrance and relatively large, mildew resistant, foliage.

This present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by crossing the unpatented variety Precilla with the variety Bridal Pink, U.S. Plant Pat. No. 2,851.

The primary objective of this breeding was to produce a new rose variety of the floribunda class with larger flowers than Bridal Pink and with some yellow pigments in the flower petals, compact plant. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:

1. Compact, upright plant habit;

2. Relatively large foliage;

3. Large flowers borne in clusters and singly on a stem;

4. Delicate coloring of pink, white and yellow;

5. Distinct fragrance;

6. Large flowers for the floribunda class; and

7. Reasonably good resistance to rose powdery mildew.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated:
